Motorcomm YT6801 Ethernet not working on Debian / Proxmox (N100 / N150 Mini PC)
✅ Solution: Use a USB Ethernet adapter (recommended) or replace the network controller.
This repository documents the investigation, diagnosis and practical solutions for this compatibility issue.
Many N100 and N150 mini PCs use the Motorcomm YT6801 Ethernet controller.
Under Linux, Debian 13 and Proxmox VE, this Ethernet interface is often not detected because no driver is available in the standard kernels.
This document explains the Motorcomm YT6801 compatibility issue on Linux and provides practical solutions for Debian and Proxmox installations.
Hardware
Mini-PC : Ninkear N150 (Alder Lake-N)
Ethernet controller :
Motorcomm Microelectronics YT6801 Gigabit Ethernet Controller PCI ID : 1f0a:6801
Detected with:
lspci -nn
Result:
01:00.0 Ethernet controller [0200]: Motorcomm Microelectronics YT6801 Gigabit Ethernet Controller [1f0a:6801]
Wi-Fi controller:
Realtek RTL8821CE Goal
Install:
Debian 13 (Trixie)
then Proxmox VE
and use the built-in Ethernet interface (YT6801).
Problem
After installing Debian:
ip a
Output:
lo wlp2s0
The Ethernet interface does not appear.
However the hardware is detected by PCI.
Diagnosis
The system detects the Ethernet controller:
Motorcomm YT6801 [1f0a:6801]
But the Linux kernel does not provide a driver for this PCIe controller.
Checking kernel configuration:
grep -i motorcomm /boot/config-$(uname -r)
Result:
CONFIG_MOTORCOMM_PHY is not set
Meaning:
only the PHY layer driver exists
the MAC PCIe driver for YT6801 is missing
Solutions tested (not working) Kernel upgrade
Installed a newer kernel:
Linux 6.19.8
After reboot:
uname -r 6.19.8-061908-generic
But:
ip link
still shows only:
lo wlp2s0
No Ethernet interface.
Loading Motorcomm PHY module
The kernel contains:
motorcomm.ko
Loading it:
modprobe motorcomm
Result:
No Ethernet interface appears.
Reason:
motorcomm.ko is only a PHY driver not the PCIe MAC driver required for YT6801 Compiling external drivers
Several drivers found online were tested:
Motorcomm driver archives
GitHub repositories
community patches
Results:
repositories unavailable
archives invalid
driver incompatible with modern kernels
compilation errors
Example:
fuxi-gmac-phy.o error Error 2 Conclusion
The controller:
Motorcomm YT6801
is not currently supported by the standard Linux kernels used by Debian or Proxmox.
The kernel includes only:
Motorcomm PHY driver
but not the full PCIe Ethernet driver.
Therefore no Ethernet interface can be created.
Practical solutions
After extensive testing, only two practical solutions exist.
Option 1 — USB Ethernet adapter (recommended)
Use a USB-Ethernet adapter based on a chipset well supported by Linux.
Recommended chipsets:
Realtek RTL8153 ASIX AX88179
Advantages:
works immediately
supported by Debian and Proxmox
stable for servers
inexpensive (~10-15 €)
After connecting:
ip a
Example interface:
enxXXXXXXXX
This interface can then be used by Proxmox.
Option 2 — Replace the network card
Replace the Motorcomm controller with a supported one:
Examples:
Intel I225 Intel I226
Limitations:
depends on mini-PC design
sometimes impossible (soldered controller)
requires hardware modification
Recommendation for Proxmox servers
For a homelab or server:
network stability is critical
experimental drivers are risky
Therefore the most reliable solution is:
use a USB Ethernet adapter Summary
Hardware:
Motorcomm YT6801 Ethernet controller
Problem:
no driver available in Debian / Proxmox kernels
Working solutions:
- USB Ethernet adapter
- Replace network controller Keywords
